Title: Fusion bonding detection method of electric fusion bonded joint for thermoplastic pipe
Inventor: KITAO KOICHI
IPC: B29C65/00
Filed: 1989-12-13
Abstract: PURPOSE:To prevent the material deterioration and lowering of material strength, by a method wherein, the resin located in the vicinity of electric heat generating body is molten by the electric heat generating body, while the molten resin is flowed to a duct inlet opened on the periphery of the joint by a generated stress, and variations in the periphery due to shrinkage of the joint are detected. CONSTITUTION:A wire 6 for the measurement at the time of the expansion of plastic tube joint 1 at outer periphery is pulled out by the pulley of the displacement gage 7. When the outer periphery of the plastic tube joint 1 is shrunk momentarily by the release of the thermal stress, the wire 6 for measurement is rewound round the pulley of the displacement gage 7, which revolves, resulting in the generation of electric pulses by the pulse generator built in the displacement gage 7. The generated pulse is led to an arithmetic unit 8, discriminates the state of the electric pulses at the time point of the momentary shrinking, generates a signal to stop the power to be supplied to the electric heating resistor 2, by the function of the devices 9 which impresses power. Because of the above structure, the lowering of the strength of the joint part by the material deterioration caused by the over-heating does not occur. By the above consideration, the material deterioration, caused by the over-heating, at the part of the joint, together with the lowering of the material strength are prevented.

Abstract: PURPOSE:To facilitate adjustment of rollers and reduce abnormal wear of rollers by mounting rollers rotating on guide face of each guide rail freely rotatably on a wheel shaft in linear form, and supporting the wheel shaft on an elevator body with metal supports detachably fixed. CONSTITUTION:When an adjustment plate 24 is so inserted that one of the rollers 13, 13 at both ends of a wheel shaft 21 may be in contact with a guide face 2a of a guide rail 2, the full rotating faces of rollers 13, 13 at both ends touches the respective guide faces 2a. Then, a metal support 22 is so moved in the length direction of the guide rail for a minute distance that the one roller 13 is in parallel to the length direction of the guide rail and then it is fixed to a frame 1a with a bolt 23. Accordingly, the rollers 13 on both sides can be placed in parallel to each other. The three-dimensional adjustment of the one roller 13 is thus unnecessary. A guide device can be installed in high precision only by two-dimensional adjustment.
